Dengue fever is not to be taken lightly, but compared to malaria, it is a far less deadly mosquito-transmitted disease. Unfortunately, the illnesses tends to share very similar starting symptoms, causing frequent misdiagnoses in areas endemic for both diseases. Now new research is showing that these mistakes not only impact individual patients, but could be helping malaria become an even greater danger.
If cats could buy records and EPs, what do you suppose would be at the top of the charts? In a new study linking various musical tempos and styles with cat attention, researchers found that they could compose music that felines would find pleasing - heavy with sliding notes and "purring" tempos.
March is upon us, and that means that scientists at the French-Italian Concordia research station in Antarctica are in the midst of prepping for a harsh winter - one that lasts half a year, with little to no contact with the rest of the world. What's worse, four of those six months will be spent without sunlight. Ah, the things some people will do for science.
We all worry about Alzheimer's disease from time-to-time, especially if we've had the unfortunate experience of watching a loved one suffer from it late in life. Now new research has revealed that a key hallmark of the encroaching disease, the accumulation of an abnormal protein in the brain, can start in people as young as 20 years old - younger than scientists ever imagined.
Birds don't seem all that smart. Despite being experts in the air, flying better than anything humanity has ever constructed, they still collide with a stunning number of cars and planes. Past studies have even revealed that a whopping 340 million birds have fatal run-ins with windshields annually. And yet, pigeons seem to never hit a single telephone pole, cable, flag post, or anything else a cityscape can throw at them. How can this be? A new study of mid-flight behavior has the answer.
A deadly fungus that has been ravaging amphibian populations across the world has somehow found its way to the isolated island of Madagascar, according to new surveys. And that's the stuff of nightmares for conservationists, as the island happens to boast countless frog species, 99 percent of which can be found nowhere else in the world.
Lyme disease: it's a pain for people both figuratively and physically. And for as long as the disease has been around, people have placed the blame squarely on the deer tick. Now new research has revealed that birds, of all things, should also be sharing a great deal of the blame, as they serve as ideal incubators and distributors of the disease.
Picture Old Faithful, the iconic geyser that erupts on a clockwork-like schedule every 91 minutes in Yellowstone National Park. Researchers have long studied this geyser, as it is an intriguing example of the natural phenomena and provides key clues as to how geysers may work. However, not every geyser is as predictable as this good ol' cone geyser, and until now the various forces behind their impressive displays remained a mystery.
It's an iconic image: a wrinkled great-grandmother hovering over a swollen belly while she dangles a needle on thread. "It's a boy" or "it's a girl," she'd proclaim without any real idea of what she's talking about. Scientists have long argued that there is no sure-fire way to determine an unborn child's gender. Even ultrasound can get it wrong. For lemurs, however, all it might take is a sniff of strong motherly BO.
"What goes around comes around," may be a common adage used by people, but new research has revealed that it's not a belief exclusive to humans. Rats, or at least ones in Norway, it seems, believe in doing favors when they are due as well, returning kindness shown to them by other rats in the past.
Cuba is facing a widespread and deadly epidemic of the Human Immunodeficiency Virus (HIV) that can progress into AIDS some three times faster than the most common strains of the virus. Now researchers have identified what makes this HIV different and deadlier than most.
Well... sort of. What we're really talking about here are the main components of those human vices - nicotine and caffeine - which are normally toxic to our tiny pollinator friends. However, much like some bird species that intentionally consume poisons to kill off intestinal parasites, small concentrations of these toxins could indeed help protect hives from illness
Bottlenose dolphins are iconic sea creatures, with thousands of vacationers flocking to the Mediterranean's clear waters to watch playful pods in action each year. Now, however, it has been revealed that these dolphins would not be found there thousands of years ago, making them relatively new settlers to the biblical "Great" or "Middle Sea."
For more than a decade, a vial of rare snake venom has been sitting in a lab while scientists stared it down, scratching their heads in wonder. Understanding how exactly a toxin works is a very important step in creating an antivenin (antivenom) for snake bites. However, in the case of rare coral snakes, how it caused severe seizures in its victims had remained an utter mystery, until now.
Mushrooms look like peaceful things, minding their own business as they soak up valuable nutrients from the soil around them. However, a rare few kinds of mushrooms are secret killers, lacerating, poisoning, or even strangling hidden prey as they innocently stand around. Now researchers have determined that one of these silent assassins gets the job done with nanoscopic "cookie cutters."
